Problems solved by technology

Second, because the ROI is automatically generated, if something goes wrong, everyone will receive an error message, which cannot be corrected at the receiver
Third, metadata needs to be sent along with the video signal, which therefore increases the bitrate

Embodiment Construction

[0017] The present invention advantageously provides a method, apparatus and system for generating a region of interest (ROI) in video content. Although the invention will be described primarily within the context of a broadcast video environment and receiver equipment, the specific embodiments of the invention should not be viewed as limiting the scope of the invention. Those skilled in the art will recognize and be informed by the teachings of the present invention that the concepts of the present invention can be advantageously applied in any environment and or receiving and transmitting method for generating regions of interest (ROI) in video content. in the device. For example, the concepts of the present invention can be implemented in any device configured to receive / process / display / transmit video content, such as portable handheld video playback devices, handheld TVs, PDAs, cellular phones with AV capabilities, portable computers, transmitters , server, etc.

Abstract

A method, apparatus and system for generating regions of interest in a video content include identifying the program content of received video content, categorizing the scene content of the identified program content and defining at least one region of interest in at least one of the characterized scenes by identifying at least one of a location and an object of interest in the scenes. In one embodiment of the invention, a region of interest is defined using user preference information for the identified program content and the categorized scene content.

Description

technical field [0001] The present invention relates generally to video processing, and more particularly to systems and methods for generating regions of interest (ROIs) in video content, particularly for display in video playback devices. Background technique [0002] Mobile and handheld devices with video displays have become popular in recent years. However, due to their small size, most handheld devices cannot display video or images at high resolution. Typically, after a handheld device receives a video signal, such as from broadcast standard definition (SD) or high definition (HD), the video must be down-sampled to the dimensions of the handheld's screen resolution, to a common intermediate format (Common Intermediate Format, CIF) or even quarter common intermediate format (quarter common intermediate format, QCIF). CIF is generally limited to a quarter of the 'full' resolution of the video system it is intended for. [0003] Due to such size reduction, sometimes t...
